To describe previously unreported clinical characteristics of persistent placoid maculopathy, suggest a pathogenesis of persistent placoid maculopathy using multimodal imaging, and provide evidence supporting high-dose immunosuppression for short-term management.
Retrospective case series.
The cohort included 3 men with ages ranging from 55 years to 68 years. Persistent placoid maculopathy was bilateral in all 3 patients and characterized by recurrence and choroidal neovascularization in 1 patient. The median time to presentation was 3 months (range, 2–24 months), and follow-up was 8 months (range, 3–24 months). Previously unreported findings of far-peripheral lesions and optic nerve hyperfluorescence on fluorescein angiography were noted in separate individuals. In addition, findings from multimodal imaging supported an inflammatory pathogenesis of the inner choroid and the outer retina. Finally, all patients experienced substantial improvement to structural and functional measures in at least one eye within days to weeks of initiating high-dose corticosteroids (0.75–1 mg/kg/day).
Multimodal imaging suggests that persistent placoid maculopathy has an inflammatory pathogenesis that may affect the inner choroid with secondary changes to the retinal pigment epithelium and the outer retina. High-dose corticosteroids may provide short-term benefit.
Persistent placoid maculopathy is a rare bilateral maculopathy. Multimodal imaging supports an inflammatory pathogenesis. Treatment with high-dose corticosteroids may be beneficial.
